Some of the injured children were barely old enough to walk. Some had the most horrendous injuries. I saw doctors peel back the shattered knee-cap of a young girl who can’t have been older than nine - she barely flinched.

There was so much that I couldn't bear to watch. At times I was surrounded on all sides by wailing and the most gruesome scenes imaginable.

This is the true cost of this Gaza conflict. The innocent caught between Hamas fighters who Israel accuses of using civilians as human shields, and the Israeli Defence Force, which is remorseless in its prosecution of this war.

The arguments will rage about whether Hamas was using this UN compound to launch missiles and whether the IDF’s warning to civilians to leave was adequate.

But for now, please set aside the politics and think of those poor children, whose haunting faces will stay with me forever.
